Before you begin
Notes
A few notes about this script.
If you are running this with the 2022-2023 data make sure you download the whole (OSM_2022-2023 GitHub repository)[https://github.com/ACMElabUvic/OSM_2022-2023] from the ACMElabUvic GitHub. This will ensure you have all the files, data, and proper folder structure you will need to run this code and associated analyses.
Also make sure you open RStudio through the R project (OSM_2022-2023.Rproj) this will automatically set your working directory to the correct place (wherever you saved the repository) and ensure you don’t have to change the file paths for some of the data.
Lastly, if you are looking to adapt this code for a future year of data, you will want to ensure you have run the ACME_camera_script_9-2-2024.R or .Rmd with your data as there is much data formatting, cleaning, and restructuring that has to be done before this code will work.

In order to get plots that have the same formatting as last years’ report we have to do a bit of data formatting. First we need to make sure we are including the same relevant species (some were ignored for last years’ report or grouped together)
Last years report had the following species
- white-tailed deer
- snowshoe hare
- black bear
- coyote
- red squirrel
- fisher
- unknown
- moose
- lynx
- spruce grouse
- red fox
- striped skunk
- ruffed grouse
- owl
- grey wolf
- domestic dog
- cougar
- raven
- other
- mule deer
And they grouped all humans except for staff as ‘Humans’. Let’s look at the species we have in this year’s data and try to format it the same way
detections %>%
# group by array and species
group_by(array, species) %>%
summarise(n = n()) %>%
# have R print everything
print(n = nrow(.))## `summarise()` has grouped output by 'array'. You can override using the
## `.groups` argument.## # A tibble: 119 × 3

Can you make the above code into a forloop which assigns each new data frame created from subsetting as dets_LUname?
Detection plots
Detection data
Now we can apply the same data formatting for each LUs’ data frame using purrr.
We want to count the number of independent detections per species per LU to use in the detection plots
# apply the same formatting to each LU data frame using purrr map
detection_data <- list(dets_LU1,
dets_LU13,
dets_LU15,
dets_LU21) %>%
purrr::map(
~.x %>%
# group by species
group_by(species) %>%
# calculate a column with unique accounts of each species
mutate(count = n_distinct(event_id)) %>%
# keep just the columns we need
select(species, count) %>%
# keep only unique (distinct) rows so we should be left with one row per species, this helps with plotting later if you don't do it ggplot will try to count and plot each row it's annoying
distinct()) %>%
# set names of list objects
purrr::set_names('Detections LU01',
'Detections LU13',
'Detections LU15',
'Detections LU21')Detection plots
Now to graph independent detections for each LU using purrr, this avoids a TON of code repetition needed to plot each one individually
We use purrr::imap() instead of
purrr::map() because imap maintains the variable names in
our list (e.g. Detections LU01, Detections LU13, etc.) which we can then
use to title each plot.
Within purrr::imap() we just paste the code we would use
for a single ggplot since all the graphical elements (except the title
which we change with the file name [.y]) are the same
# create object detection plots which uses the detection_data list (w/ all 4 LUs)
detection_plots <- detection_data %>%
# use imap instead of map as it allows us to use .y to paste the list element names as the plot titles later
purrr::imap(
~.x %>%
# now just copy and paste the ggplot code for the detection graphs
ggplot(.,
aes(x = reorder(species, count), y = count)) +
# plot as bar graph using geom_col so we don't have to provide a y aesthetic
geom_col() +
# switch the x and y axis
coord_flip() +
# add the number of detections at the end of each bar
geom_text(aes(label = count),
color = "black",
size = 3,
hjust = -0.3,
vjust = 0.2) +
# label x and y axis with informative titles
labs(x = 'Species',
y = 'Number of Independent (30 min) Detections') +
# add title to plot with LU name the .y will take the name of whatever you named each list element in the detection_data list, so make sure this name is what you want on the ggtitle
ggtitle(.y) +
# set the theme
theme_classic() +
theme(plot.title = element_text(hjust = 0.5)))
# view plots, this will print each in it's own window so you have to scroll back in the plot viewer pane to look at each one

Save detection plots
Now we want to save these plots in case we need each individual one (we will combine the detection and naive occ plots into a single figure for each LU later and use those for the OSM report, but we may want these standalone plots later so let’s save them while they are here).
We can save all the plots from the purrr iteration above using
purrr::imap. imap is used instead of map because it allows
us to retain the list object names (plot names) to paste as the file
name with the .y command.
IMPORTANT if you are using this code for a future github repo, DO NOT use .tiff as the file extension. This will cause issues when trying to push any changes to the github repo as the files are too large to meet githubs requirements
# save plots only use if needed
purrr::imap(
detection_plots,
~ggsave(.x,
file = paste0("figures/",
.y,
'.jpg'), # avoid using .tiff extension in the github repo, those files are too large to push to origin

units = 'in'))## $`Detections LU01`

Data
We also need to alter the detection data a bit to use for naive occupancy plots.
We will use the individual LU detection data like we did before and
use purrr::map() to apply the dame data formatting to all 4
data frames.
Here we want to calculate the total number of sites in each LU, the number of sites each species was detected at in each LU and then use both those numbers to calculate naive occupancy for each species in each LU
# First we need to alter the data frame a bit for these plots, let's create a data frame for each LU (I couldn't figure out how to do this without assigning individual data frames for each UGH)
# apply the same formatting to each data frame using purrr
occupancy_data <- list(dets_LU1,
dets_LU13,
dets_LU15,
dets_LU21) %>%
purrr::map(
~.x %>%
# calculate the total number of sites for each LU
mutate(total_sites = n_distinct(site)) %>%
# group by species to calculate the number of sites each spp occurred at
group_by(species) %>%
# add columns to count the number of sites each spp occurred at and then the naive occupancy
reframe(count = n_distinct(site),
naive_occ = count/total_sites,
ind_det = n_distinct(event_id)) %>%
# keep just the columns we need
select(species, naive_occ, ind_det) %>%
# keep only unique (distinct) rows so we should be left with one row per species, this helps with plotting
distinct()) %>%
purrr::set_names('Naive Occupancy LU01',
'Naive Occupancy LU13',
'Naive Occupancy LU15',
'Naive Occupancy LU21')Occupancy plots
Now we can graph naive occupancy for each LU using purrr, and as with the detection plots this saves a massive amount of coding using purrr to run an iteration on the data files and produce four plots at once instead of copying and pasting code for each individually
# create object occupancy_plots which uses the occupancy_data list (w/ all 4 LUs)
occupancy_plots <- occupancy_data %>%
# use imap instead of map as it allows us to use .y to paste the list element names as the plot titles later
purrr::imap(
~.x %>%
# now just copy and paste the ggplot code for the occupancy graphs
ggplot(.,
aes(x = fct_reorder(species,
ind_det), # this reorders the species so they match the order of the detection plot which makes it better for viewing when the plots are arranged together in 1 figure for each LU
y = naive_occ)) +
# plot as bars using geom_col() which uses stat = 'identity', instead of geom_bar() which will count the rows in each group and plot that instead of naive occ
geom_col() +
# flip x and y axis
coord_flip() +
# add text to end of bars that provides naive occ value
geom_text(aes(label = round(naive_occ, 2)),
size = 3,
hjust = -0.3,
vjust = 0.2) +
# relabel x and y axis and title

later for something so we can use purrr::imap() to save
them to the figures folder

The previous year’s report had a figure for each LU with the
detections plot on the top and the occupancy plot on the bottom so we
will recreate these for this year using ggarrange().
Unfortunately I could not figure out how to do this in purrr to reduce coding but luckily it isn’t too much repitition
# not sure I know how to do the following section in purrr just yet, but we've saved a ton of coding so far and it doesn't take much to arrange each of these individually

# arrange the plots so each LU has a figure with detections on top and naive occ on bottom

## - attr(*, "problems")=<externalptr>Format covariates
There are too many covariates to include in the models individually and many of them describe similar HFI features. We can use the info from the README file in this repository which includes detailed descriptions from the ABMI human footprints wall to wall data download website for Year 2021 OR in the relevant_literature folder of this repository (HFI_2021_v1_0_Metadata_Final.pdf).
the current version of this code for the purposes of the 2022-2023 report used a merged dataset from 2021-2022 and 2022-2023 data, howver each year of data the variables were extracted slightly differenty from GIS so final version of this code will include a different formatting process which will likely occur in the ACME_camera_script_9-2-2024.R or .Rmd

add more to this section in later when we have more time to explore the covariates and choose which should be inlcuded etc.
hfi_histograms <- buffer_frames %>%
purrr::imap(
~.x %>%
# filter to just the HFI variables
select(where(is.numeric) &
! starts_with('lc_class')) %>%
# pipe into hist.data.frame function to make histograms for each variable
hist.data.frame(mtitl = paste0('Histograms of HFI variables at ', .y)))
Now let’s do the same thing with the landcover variables
lc_histograms <- buffer_frames %>%
purrr::imap(
~.x %>%
# filter to just the landcover variables
select(where(is.numeric) &
starts_with('lc_class')) %>%
# pipe into hist.data.frame function to make histograms for each variable
hist.data.frame(mtitl = paste0('Histograms of landcover variables at ', .y)))
Add response metric
Now that we have the covariate data formatted we need to add the response metric (monthly proportional presence/absence) to the data frames
final_df <- buffer_frames %>%
purrr::map(
~.x %>%
left_join(prop_detections,
by = 'site'))Analysis
Now we are going to run a global model which includes all HFI and LC variables that at first glance (will do a more thorough check later) seem to have enough data to include as covariates for each buffer width, and then we will compare these models see which buffer width best fit the data for each species.
We don’t need to do ALL the species since many don’t have enough data.
Refer to the ACME_camera_script_9-2-2024.html or .Rmd the plot for proportional monthly detections should provide info on which species we have enough data for, can be found under Response metrics/3.Proportion monthly detections
A brief look at this fig indicates that we have enough for all the mammals in the prop_detections data frame except
- cougar
- wolverine
- caribou??? (may have enough may not)
Black bear
ANDREW/MARISSA FIX later
there is probably a way to shorten the following code to select particular species, I saw Andrew’s for loop in the draft script he wrote but couldn’t quite figure it out so I did this instead, maybe we can merge approaches?
Global model
Let’s start with bears and use purrr to create a global model for every buffer distance
black_bear_mods <- final_df %>%
# use purrr map to fun the same functions for all buffer sizes ((all objects in list))
purrr::map(
~.x %>%
# glmmTMB function let's us run the proportional binomial model using cbind to combine the present and absent columns for each species

We will use the model.sel() function from the
MuMIn package to compare the global models for each buffer
width and see which buffer fits the bear data best

## cond(1 | array)hmmmm seems fishy to me that the 250 meter buffer which is the only one that had missing data would perform THAT much better than all the others, and really you shouldn’t compare models if they aren’t run on the same data, hence the warning message
Let’s remove the 250 buffer and see what happens
black_bear_mods_no250 <- black_bear_mods %>%
# purrr::discard_at will remove an item from a list
purrr::discard_at('250 meter buffer')

So what we will do for each species is remove the 250 meter buffer for now since there are some data missing. and compare just the other buffer sizes that contain the full data set

We can use the same code from black beasr (above) to run global models for each buffer width except remember we want to remove 250 meters
And in the same chunk to save time let’s also run the
